Fixed bug 9905: Failure in code selection for llvm intrinsics sqrt/exp (fix for
FSQRT, FSIN, FCOS, FPOWI, FPOW, FLOG, FLOG2, FLOG10, FEXP, FEXP2). Second
attempt.

fed4d19edd Make CR spill and restore use a reserved register. These operations cannot use the register scavenger because the scavenger can only scavenge one register and frame-index elimination may have already grabbed it.

77caaf0fc0 Try to align the point where a large basic block is split. 
The split point is picked such that the newly created water has the same
alignment as the function. This makes the island suitable for constant
pool entries with potentially higher alignment.

This also fixes an issue where the basic block was split one instruction
too late, causing nonconvergence of the algorithm.

<rdar://problem/10550705>

There is still an issue with correctly packing differently aligned
entries in the island.

f3aefb56de Handle expressions of the form _GLOBAL_OFFSET_TABLE_-symbol the same way gas 
does. The _GLOBAL_OFFSET_TABLE_ is still magical in that we get a R_386_GOTPC,
but it doesn't change the immediate in the same way as when the expression
has no right hand side symbol.

8a12e3b5df ARM allows '' syntax, not just '#imm' for assembly. 
Backwards compatibility with 'gas'. #imm is the preferered and documented
syntax, but lots of existing code uses the '$' prefix, so we should
support it if we can.

840bf7eda7 ARM assembly aliases for BIC<-->AND (immediate). 
When the immediate operand of an AND or BIC instruction isn't representable
in the immediate field of the instruction, but the bitwise negation of the
immediate is, assemble the instruction as the inverse operation instead
with the inverted immediate as the operand.

a4e3c7fc4b ARM assembly parsing and encoding for VLD2 with writeback. 
Refactor the instructions into fixed writeback and register-stride
writeback variants to simplify the offset operand (no more optional
register operand using reg0). This is a simpler representation and allows
the assembly parser to more easily handle these instructions.

Add tests for the instruction variants now supported.

2f435511e9 Many of the SSE patterns should not be selected when AVX is available. This led to the following code in X86Subtarget.cpp 
if (HasAVX)
    X86SSELevel = NoMMXSSE;

This is so patterns that are predicated on hasSSE3, etc. would not be selected when avx is available. Instead, the AVX variant is selected.
However, this breaks instructions which do not have AVX variants.

The right way to fix this is for the SSE but not-AVX patterns to predicate on something like hasSSE3() && !hasAVX().
Then we can take out the hack in X86Subtarget.cpp. Patterns which do not have AVX variants do not need to change.

However, we need to audit all the patterns before we make the change. This patch is workaround that fixes one specific case,
the prefetch instructions. rdar://10538297
